Method and steps for cleaning the microscope
Cleaning precision optical devices may reduce their performance, and improper or unnecessary cleaning can easily damage the surface coating of the device. Properly removing and storing the device in a dedicated container will minimize the number of cleaning cycles and the possibility of device damage.
A. Recommend cleaning materials, polyethylene laboratory gloves, optical grade lens cleaning paper, degreased long staple cotton, and proportioning alcohol and ether solutions according to the environment for surface cleaning of optical components.
The recommended ratio is as follows: a room temperature: 35% ethanol at 18 ℃ -24 ℃, 65% ether; b room temperature: 25% ethanol at 12 ℃ -18 ℃, 75% ether
B. Recommended cleaning steps
1. Blow off surface dust with clean air. If it cannot be blown clean, wrap two sheets of lens paper on a cotton swab or fold the lens paper so that it is slightly larger than the area to be cleaned.
2. When wiping the surface of optical components, the rough sand surface and frame should first be wiped clean with petroleum ether.
3. When wiping circular parts, the cotton ball should move in a spiral line from the center to the edge. At the same time, the cotton ball itself should also rotate and move it out of the surface of the lens, without staying at the edge of the lens to avoid leaving marks. If using a rotary device to wipe, the cotton ball should move in a straight line from the center to the edge, and the cotton ball itself should rotate simultaneously (the rotation of the cotton ball should be slightly less than one circle).
4. When wiping the prism, a cotton ball can be placed horizontally on the surface to be wiped and wiped in a straight line.
5. It should be wiped in a relatively clean room and wiped with degreased long staple cotton. The cleaning solution on the cotton ball should not be too much. When wiping, it should be moved and wiped in the cross direction of the reticle to avoid wiping off the filling layer inside the reticle.
6. When wiping the glued optical parts, the cotton ball should not be dipped in too much mixture to prevent solvent from invading the glued layer and causing delamination.
7. Reflective parts coated with aluminum and protective film can be wiped with a cotton ball dipped in a small amount of mixed liquid or a carefully degreased sandcloth if the protective film is relatively firm.
8. The cotton ball should be rolled well, and the head of the bamboo stick used to roll the cotton ball should not be exposed to avoid scratching the parts. The size and shape of cotton balls should vary depending on the size and type of parts. Generally, cylindrical cotton balls are used for circular parts, flat cotton balls are used for flat parts, and soft cotton balls are used for coating surfaces (especially reflective magnesium). In other cases, the cotton balls should be tightly rolled.
9. When the cotton ball dipped in the mixture enters the solvent, please do not exceed one-third of the length of the cotton ball.
